摘要：
In the illustrative embodiment of a current-carrying pneumatic spring disclosed, flow of electric current between external terminals on the cylinder member and piston rod member of the spring is provided by a contact element fixed on one of the members and carrying one or more contact faces which are resiliently biased into sliding engagement with an axially elongated face portion of the other member. Flow of electric current between the external terminals may thereby be provided over a range of positions or over all positions of axial movement of the piston rod member inward and outward of the cylinder cavity.
